METHOD OF DIE FORMING WITH ROLLING AND DEVICE FOR IMPLEMENTATION OF THIS METHOD Russian patent published in 2008 - IPC B21D37/12 

FIELD: metallurgy.

SUBSTANCE: method of press forming with rolling includes placement of stock in matrix set on die plate and rolling of stock with rolling press connected to drive which transfers oscillatory movement to rolling press when it is pressed to stock with force. The rolling press is equipped with a gear sector, and the die plate is equipped with a gear rack. When the stock is rolled with the rolling press, gears of the gear sector are in constant mesh with gears of the gear rack to facilitate rolling conditions. The device for die forming with rolling contains the rolling press and the matrix, installed on the die plate for stock placement thereon. The drive of the device connected to the rolling press facilitates pressing of the rolling press to the stock with force, the drive also transfers oscillating movement to the rolling press for rolling the stock with a working surface of the rolling press. The rolling press is equipped with the gear sector, and the die plate is equipped with a gear rack corresponding to the gear sector. The gears of the gear sector are designed to mesh with the gears of the gear rack.

EFFECT: there is facilitated reduction of maximum force of die forming and of speed of rolling.
